OLD GOLDEN GATE

After the Theodosian land walls had been built, the wall of Constantine
quickly fell in ruins. The only part of it that is known to have survived
for a longer time is the old main or Golden Gate, that survived until the
ottoman time and was destroyed by a earthquake only in 1509. The medieval
name (H)exakionion means "with six columns"; it suggests that the gate was
similar to the Golden Gate of Diocletian's palace in Split and had a upper
storey decorated with six columns and niches in between on the outer side.
In the last centuries of the Byzantine Empire, this upper storey
apparently was used as a funerary chapel, and parts of the building
decorated with frescoes.
